Abstract

The invention belongs to the field of chemical engineering equipment, and relates to a reaction kettle, in particular to a single screw type conical reaction kettle. The screw type conical reaction kettle comprises a kettle body, a kettle cover and a stirring rod, and is characterized in that the kettle body adopts an inverted cone structure, a motor is mounted at the center part of the kettle cover, the lower end of the motor is connected with a speed reducer, a main drive box is mounted at the lower part of the speed reducer, one end of the main drive box is connected with a transverse drive shaft which is connected with an auxiliary turning box, the auxiliary turning box is connected with the stirring rod, and the stirring rod is parallel to the kettle body and is mounted close to the wall of the kettle; a spiral filament is welded on the outer wall of the stirring rod, and a manhole is formed in the kettle cover; and bracket bases are arranged on the kettle body, and a discharge valve is arranged at the bottom of the kettle body. The stirring rod can revolve under the drive of the main drive shaft and can perform autoroatation under the drive of the auxiliary turning box, and the spiral filament on the stirring rod can effectively shear a viscous material in the autoroatation and revolution process, so that the material around the spiral filament turns to be uniformly mixed, and the reaction kettle is particularly suitable for producing the viscous material.

Description

technical field [0001] The invention belongs to the field of chemical equipment, and relates to a reactor, in particular to a single-screw conical reactor. Background technique [0002] The reaction kettle is an important reaction equipment in the production of pharmaceuticals and fine chemicals. There are many types of reaction kettles. The body of the reaction kettle is a cylindrical structure, and the upper and lower heads are installed; the stirring types include frame type, riveting type, paddle type, etc. . For different material reactions, it is necessary to select the corresponding reactor and stirring type. [0003] In the production of pharmaceuticals and fine chemicals, unit reactions with viscous materials are often encountered. If the above-mentioned common reactor and stirring type are used, there will be uneven reaction mixing, large power consumption, motor burnout, and deformation of the stirring device. , leading to equipment damage and seriously affectin...
